About stdlib...
We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.
The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.
When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, wellwritten, studied, documented, tested, measured, and highquality code out there.
To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!
Return a string giving the literal bit representation of an unsigned 16bit integer.
npm install @stdlib/numberuint16basetobinarystring
var toBinaryString = require( '@stdlib/numberuint16basetobinarystring' );
Returns a string
giving the literal bit representation of an unsigned 16bit integer.
var Uint16Array = require( '@stdlib/arrayuint16' );
var a = new Uint16Array( [ 1, 4, 9 ] );
var str = toBinaryString( a[0] );
// returns '0000000000000001'
str = toBinaryString( a[1] );
// returns '0000000000000100'
str = toBinaryString( a[2] );
// returns '0000000000001001'

Except for typed arrays, JavaScript does not provide native user support for unsigned 16bit integers. According to the ECMAScript standard,
number
values correspond to doubleprecision floatingpoint numbers. While this function is intended for unsigned 16bit integers, the function will accept floatingpoint values and represent the values as if they are unsigned 16bit integers. Accordingly, care should be taken to ensure that only nonnegative integer values less than65536
(2^16
) are provided.var str = toBinaryString( 1 ); // returns '0000000000000001' str = toBinaryString( 4 ); // returns '0000000000000100' str = toBinaryString( 9 ); // returns '0000000000001001' str = toBinaryString( 65535 ); // returns '1111111111111111'

@stdlib/numberfloat64/base/tobinarystring
: return a string giving the literal bit representation of a doubleprecision floatingpoint number.
This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
